1 Sample assessment task Aviation ATAR Year 12 Task 1 Unit 3 Assessment type: Test Conditions Time for the task: 60 minutes Task weighting 4% of the school mark for this pair of units Meteorology test Multiple-choice (30 marks) (10 marks) 1. At which of the following levels of the atmosphere is the temperature most likely to be at approximately 57 C? bottom of ionosphere top of ionosphere top of stratosphere top of troposphere 2. Which cloud type would best describe a 1400 feet deep layer that an aircraft encounters at a height of about 15 000 feet? cirrostratus altocumulus altostratus stratocumulus 3. When air masses of different temperatures and densities come together, their boundary is called a trough. cyclone. front. convergence zone. 4. In the southern hemisphere, the geostrophic wind flows at 10 towards the higher pressure over land. along curved isobars. at 30 towards the lower pressure over land. along straight isobars.

2 5. The common link between sea breezes, katabatic winds and anabatic winds is that they are all light winds. local winds. cool winds. dry winds. 6. Updrafts are a feature of thunderstorms. In the 'life' of a thunderstorm, updrafts are most likely to exist in all stages. the developing stage. in the developing and mature stages. the mature and dissipating stages. 7. If a temperature inversion occurs in the atmosphere, then the dry adiabatic lapse rate will be less than the saturated abiatic lapse rate. temperature will remain constant with an increase in altitude. temperature will decrease with an increase in altitude. temperature will increase with an increase in altitude. 8. Which of the following statements about clouds is most accurate? Cirrus clouds are composed of ice crystals. Stratus clouds are usually present in an unstable atmosphere. Cumulus clouds are usually associated with an inversion layer. Cumulonimbus clouds usually form when fog begins to lift due to the heating effects of the sun. 9. Cloud coverage of 1 OKTAS would be described as SKT. FEW. BKN. OVC. 10.
